I'm not sure where I read this story and its been a few years but I'm looking for a story about this girl, can't remember if she was kidnapped or what, but she ends up at this house with a few guys and they are training her as a puppy slave of sorts for her master. They take time training her and later in the story her master shows up to see how the training goes. I don't know the name of the story but I've been looking for it. She has to sleep in a dog bed, goes outside for her bathroom needs, eats from a dog bowl. Any help finding this story would be appreciated.
